Title: Optical transmitter and system
Inventor: SASAI HIROYUKI
IPC: H04B10/278
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To provide the optical transmitter in which a transmission characteristic deterioration caused by a reflected light is sufficiently suppressed through a simple and inexpensive configuration in the case of transmission by the optical SCM system. SOLUTION: An oscillation section 102 provides an output of an additional signal with a frequency that is higher than a frequency in a frequency band width assigned to an electric signal to be transmitted and lower than a half of a minimum frequency in the frequency in the frequency band width assigned to the electric signal to be transmitted. Even should a secondary intermodulation distortion take place between the additional signal and the electric signal to be transmitted, the frequency of the distortion is at the outside of the frequency band assigned to the electric signal to be transmitted and then the produced secondary intermodulation distortion gives no effect on the electric signal to be transmitted.  Furthermore, should a secondary harmonic distortion of the additional signal take place, the frequency of the distortion is at the outside of the frequency band assigned to the electric signal to be transmitted and no effect of the produced secondary harmonic distortion is given onto the electric signal to be transmitted.

Title: Noise rating evaluating device
Inventor: TANIGAWA YUSUKE
IPC: H01L21/66
Filed: 1989-12-16
Abstract: PURPOSE:To generate a noise at any timing of an input and an output of an integrated circuit so that a noise rating can be evaluated quantitatively by controlling a generation time of a pulse by a tester for testing the integrated circuit. CONSTITUTION:By a tester 2, an integrated circuit 1 is operated, and VCC is applied to an input terminal A0. In this case, when the timing of a clock 4 is a high level, a transistor 5 is turned on, and turned off in the case of a low level. That is, the moment turn-off is changed to turn-on, induced electromotive force is generated in a coil L2 7. In such a way, after a noise is generated, whether outputs of data input/output terminals D1 - D4 are remarkably different from an output set by the tester 2 or not, namely, whether the noise generates a malfunction or not is measured by the tester 2. Unless the malfunction is generated, a variable voltage 8 is varied, and in the same way, the measurement is executed. This operation is repeated until the malfunction is generated, and a value of the variable voltage 8 at the time when the malfunction is generated first is detected as a noise rating of the integrated circuit 1.

Inventor: NARUSE HARUHIKO
IPC: A61G7/05
Filed: 1989-12-15
Abstract: PURPOSE:To prevent the failure from being generated even at the time when it is stopped to blow out air from an air blowout part by providing a valve which is freely openable and closeable and blows off air to the outside of a system in the course of cutting off a flow of air to the air blowout part, in an air passage extending from a pump to the air blowoff part. CONSTITUTION:The device is constituted so that when the air supply to an air blowout part 13 is stopped by a solenoid valve of a 3-port/2-position type, to a valve 43 placed between the air blowout part of a decubitus preventive mat 1 and a pump unit 3, air of the quantity taking the place thereof is blown off to the outside of a system. In such a way, even when blowout of air from the air blowout part 13 is stopped, air of the quantity taking the place thereof is blown off to the outside of the system, therefore, a vibration type diaphragm pump can be operated under almost the same condition as air is blown out of the air blowout part 13. Accordingly, the supply of air can be executed without causing control instability of the diaphragm pump, and without causing the failure in other air supply part.

Filed: 1991-11-15
Abstract: PURPOSE:To eliminate detects such as the disconnection of the wiring between elements formed on a crystal by forming a stopper layer preliminarily, by removing a region of cracks generated on a substrate whose surface is formed of amorphous insulating material and by forming such a surface as has small steps. CONSTITUTION:After forming a stopper layer 102 on the surface of a substrate 101 whose surface is made of amorphous insulating material, a layer in which a recessed part is to be formed 104 is deposited. Then, the layer 104 is partially removed to form a recessed part 112. Nextly, a crystal 110 is formed and planarized and then it is etched to the stopper layer 102 wherein cracks 115 are formed. After that, planarizing material 105 is selectively deposited only on a part from which the layer is removed to reduce the difference in height between the surface of the planarizing material-deposited region and the surface of the crystal. By this method, a circuit can be formed without defects such as the disconnection of the wiring between elements formed on the crystal and thereby the yield and the reliability of an integrated circuit can be increased.

Abstract: PROBLEM TO BE SOLVED: To equip a delay circuit join a DSP(digital signal processor) chip. SOLUTION: A core 31 transmits a PLL control signal s31 to a PLL 32 and a counter 34. The PLL 32 receives the PLL control signal s31, a VCO is operated and an oscillation is started. A counter 34 receives the PLL control signal s31 and is reset. A NOR gate 33 takes a negative OR of the output signal s34 of the counter 34 and the output signal s32 of the PLL 32 and outputs the OR to the counter 34. The counter 34 performs a count-up operation by the timing of the up edge by defining the output s33 of the NOR gate 33 as a clock and outputs all '1' when the counting is terminated. An AND gate 35 outputs the output s32 of the PLL 32 to the core 31 when the all '1' is outputted from the counter 34. When the counter 34 terminates the counting, the counter 34 stops the counting operation.
